A data encryption method. At a server the original data file is encrypted using an encryption key to create an encrypted data file, data is removed from the encrypted data file to create an altered encryption data file, the altered encrypted data file is transmitted to a remote computer, a QR code is created including the removed data and the encryption key, and the QR code is transmitted to the remote computer. At the remote computer, the removed data and the encryption key are recovered from the QR code and are used to recover the original data file.
Legal claims defining the scope of protection, as filed with the USPTO.
1. Data encryption method comprising the steps of: a. at a server: i. encrypting an original data file with an encryption key to create an encrypted data file; ii. from the encrypted data file removing x number of data characters every y number of data characters to create an altered encrypted data file; iii. capturing the removed data characters; iv. sending the altered encrypted data file to a remote computer; v. creating a QR code representing the encryption key and the removed data characters; and vi. sending the QR code to the remote computer, and b. at the remote computer: i. capturing and decoding the QR code at the remote computer to recover the removed data characters and the encryption key; ii. adding the removed data characters back into the altered encrypted data file to re-create the encrypted data file; and iii. decrypting the encrypted data file using the recovered encryption key to re-create the original data file.
